CHURN.

SPECIFICATION forming part of Letters Patent No. 642,966, dated February 6, 1900.

I Applioation filed May 6, 1899- Serial. No. 715,816. (No model.)

To all whom it may concerrt.

Be it known that I, GEORGE W. DISMAN, a citizen of the United States, residing at Lima, in the county of Allen and State of Ohio, have 5 invented new and useful Improvements in Ohurns, of which the following is a specifica-' tion.

This invent-ion relates to churns, and has for its object to provide a churn of novel, sim- I pie, durable, and inexpensive construction and which will be quick and eflicient in operation.

To these ends my invention consists in the features of construction and in the novel com- 1 5 'bination and arrangement of parts hereinafter described, and particularly pointed out in the claims following the description, reference being had to the accompanying drawings, forming a part of this specification, wherein- Figure 1 is a side view; Fig. 2, a side view, partly in section. Fig. 2 is "a detail view showing a modified manner of attaching the arched frame to the churn-body; Fig. 3, a top plan view with the bracket and gearing removed; Fig. 4, a cross-sectional view; Fig. 5, a detail of the lid-locking bar; Fig. 6, a detail perspective of the dasher.

Referring to the drawings, the numeral 1 indicates the churn-body of cylindrical form and preferably made of enameled sheet metal or sheet metal coated with aluminium. Attached to the outside of the churn is a waterjacket 2, provided at its lower end with an outlet 3. Hot or cold water, as circumstances may require, may be introduced into the jacket for increasing or lowering the temperature of the contents of thechurn. Riveted to the interior of the body of the churn are a plurality of vertical sheet-metal ribs or breakers 4, which operate as abutments against which the cream is thrown by the dasher and the globules thereby broken up. Riveted to the opposite sides of the churnbody, just beneath the upper edge thereof, are two brackets 5, each consisting ofa piece of metal bent at a right angle and curved longitudinally in the arc of a circle to correspond to the cylindrical form of the churn-body. The numeral 6 indicates a frame for supporting the dasher and gearing and comprising a metallic arch, the divergent legs 7 and 8 of which are provided at their lower ends with feet or lateral flanges 9, that are bolted or riveted to the angle-brackets 5, or thelower ends of the legs 7 and 8 may be hinged to the anglebrackets, whereby the entire frame may be thrown back for convenience in washing the churn-body, as shown in Fig. 2. The upper ends of the legs 7 and 8 converge and terminate in avertical journal-bearing 10. Looselyjour- 6o naled in the bearing 10 is a vertical dashershaft 11, having fixed on its upper end a beveled pinion 12, which is adapted to rotate on the upper end of the bearing 10 and serves to suspend the dasher-shaft in position. At a suitable point beneath the bearing 10 the legs 7 and 8 are united by a rib 13, to which is fixed a horizontally-projecting shaft 14, on which is journaled a relatively large beveled gearwheel15, that gears with the pinion 12 on the dasher-shaft and is held in place by a washer 16 and cotter-pin 17. A crank or handle 18 is fixed to the gear-wheel 15, by means of which the Wheel may be rotated.

Arranged on the upper end of the churn body is a lid or cover comprising two semicircular pieces 19, each provided with a peripheral flange 20. The sections 19 fit within the top of the churn-body, and the flanges 20 rest on the upper edge thereof. The straight 8o or adjacent edges of the sections 19 are each provided with a semicircular notch or recess 21, which when the two sections are in place form a passage and bearing for the dashershaft and operate to cause'the latter to rotate steadily. The sections 19 are each provided with a knob 22, by means of which said sections may be conveniently removed and replaced on the churn-body. The lid sections or pieces 19 are rabbeted at their circular o edges to fit down into the chu rn-bod y and rest upon the upper edge thereof. The downwardly-diverging arms or legs 7 and 8 of the arched frame 6 embrace opposite peripheral portions of the semicircular lid-sections and 5 permit the latter to be readily removed Without disturbing the arched frame, such removal of the lid being convenient and easy, in that the lid is in two sections which can be separately removed after the clamp-bar 25, heretoo inafter-described, is detached.

Bolted or riveted to the opposite upper sides of the churn-bod y are two tail-screws 23,which project above the upper edges of the churnbody, as shown, and screwed on said screws are thumb-nuts 24. Disposed over the coversections 19 is a clamp-bar 25, provided midway between its'ends with a boss 26, having a slot 27 formed in one side thereof. The bar 25 is provided on its sides near its ends with slots 28 and 29, the slot 28 being formed in the side of the bar opposite to that in which the slot 20 is formed. The slotted boss 26 embraces the dasher-shaft, and by giving a partial turn to the clam p-bar its slotted ends are caused to engage the tail-screws 23, and by screwing down the thumb-nuts 24 the clampbar is locked in position, firmly holding the cover-sections in place on the churn. In like manner by loosening the thumb-nu ts and partially turning the clamp-bar in the reverse direction the latter may be removed and the cover-sections taken off without in any manner disturbing any of the other parts.

Adjustably fixed on the lower end of the dasher-shaft 11 is a dasher 30. Said dasher consists of a flat metallic plate provided with apertures 31 and longitudinally corrugated between its sides to form a groove 32, in which the dasher-shaft lies. Formed in the dasher transversely of the groove 32 and a short distance above the lower edge of the dasher is a slit 33, and below said slit and in alinement with the groove 32 the dasher is corrugated in a reverse direction to the corrugation before referred to, forming a grooved strap 34. Riveted to the upper end of the dasher is a lug 35, having formed therein a cylindrical bearing 36, and tapped through said lug is a thumb-screw 37. The dasher-shaft 11 passes through the bearing 36 in the lug 35, along the groove 32 in the dasher, and underneath the strap 34, and by tightening up the thumbscrew 37 the dasher is firmly and rigidly fixed on said shaft. By loosening the thumb-screw the dasher may be vertically adjusted on the dasher-shaft.

In some instances a wooden dasher may be employed instead of the metallic dasher above described.

In order to remove the butter from the churn, it is desirable to lift the dasher clear of the churn-body, and in order that this may be accomplished without detaching any of the parts the upper end of the dasher is formed of inverted-V shape, whereby it may be raised up between the divergent legs 7 and 8 of the frame 6. A stationary handle 38 is fixed to one of the legs 7 or 8, which in practice the operator grasps with one hand to steady both the churn and his body, While with his other hand he turns the drive-Wheel 15, which latter in turn rotates the pinion 12 and the dasher-shaft and dasher.

Having described my invention ,what I claim is- 1. The combination with a cylindrical churn-body, of angle-brackets secured to opposite sides of the top portion thereof, the dasher-shaft, the arched frame having a bearing at its apex supporting the dasher-shaft and comprising downwardly-diverging arms having feet at their lower ends detachably secured, respectively, to said angle-brackets, the lid fitting the upper end of the churn-body between the said diverging arms and composed of two semicircular sections susceptible of being separately removed and replaced while the arched frame remains in a fixed position on the angle-brackets, and a clampbar for securing said lid-sections in position, substantially as described.

2. The combination with a cylindrical churn-body, of angle-brackets secured to opposite sides of the top portion thereof, the dasher-shaft, the arched frame having a hearing at its apex supporting the dasher-shaft and constructed with downwardly-diverging arms having feet at their lower extremities detachably secu red, respectively, to said angle-brackets, the lid having arabbeted periphery fitting down into the churn-body and resting against the upper edge thereof, said lid being composed of two semicircular sections separately removable and replaceable while the arched frame remains fixed to said angle-brackets, the clamp-bar having a central slot to fit the churn-dasher and open end slots at its extremities, the tail -screws sechred to the churn-body and adapted to engage said open end slots at the extremities of the clamp-bar, and clamp-nuts on the tailscrews, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing wit- IIBSSGS.
